Microsoft Graph is the unified API for modern work

Use the data and intelligence in Microsoft 365 to build apps that interact with millions of users.

Respond to changes in Microsoft Graph data in real time. Reschedule a meeting based on responses, notify others when a file is modified, or continue a process after it's been approved.
